Hi,
i have a levitating slur like in the attachment. Fixing slur is easy -
just change the direction of stems of bflat notes under it.
But the question is, should the direction of bflat notes outside the
slur be changed as well (i.e. the ones over "terrae")?
What's the common engraving practice?
cheers,
Janek
